Two calls yesterday (11/8/2012). Left no message. Calls were made to my Google Voice number, which I don't give out to many non-family, non-friends. Makes me suspicious.
Received call, went to voicemail as it is an unkown number. Apparently I signed up for some drawing several months ago and they are trying to reach me to process the gift I won. Their call back number is 1-866-930-1914. I did attend the event they mentioned where I submitted my contact information; however, most of these 'prizes' require a down payment for their reduced-rate trip that I 'won'. I never call them back. To me, these are telemarketers trying to sell you a time share or pots and dishes.
